Uniflow and loop scavanging with diagram... System on your ship...
Timing diagram of 2 stroke... why Fuel injected just before TDC... tried to confuse me a lot here..
Refregeration cycle Diagram and describe back pressure valve and how it functions?
and lots of cross questioning on all above questions .. and trying to create confusion...
Function 5: Electricity
Earthed neutral systems and lots of questions and is it necessary what if not earthed?

Function 6: MEP
What all work did you do onboard? told him D/G decarb, pump overhaul..
What type of filter used in bilge line draw and explain arrangement on your vessel?
why arrangement of filter cover is different?
All the checks made on piston during decarb..
Why clearence between piston ring and groove important.. explain with diagram..
How piston of 4/s is lubricated, diagram...
Function 5
1) Electrical motor before ordering what all specification to give?
2) Define frequency. Unit in which measured (didnot want to hear hz...he wanted second..f=1\t....1\s)
